Generally covariant measurement schemes for quantum field theory in curved spacetimes
- Chris Fewster (University of York, United Kingdom)
Abstract
Algebraic quantum field theory is founded on the idea of algebras of observables associated with local regions of spacetime, but not much attention has been given to how these observables can actually be measured. On the other hand, quantum measurement theory provides an operational understanding of measurement schemes for quantum observables, but is not framed in a spacetime context. This talk will describe a generally covariant formalism of measurement schemes adapted to quantum field theory in curved spacetimes, illustrated by a specific model.
